MILO J'. JOHNSON, OF MCBRIDES, MICHIGAN.

MUSIC-LEAF TURNER.

Application led June 7, 1916.

- citizen of the United States, residing at Mc- Brides, in the county of Montcalm, State of Michigan, have invented certain new and useful Improvements in Music-Leaf Turners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to music leaf turners and has for an object the provision of an appliance or mechanism designed .for universal adaptation and by which the sheets In'carrying out the invention it is my purpose to provide a music leaf turner which shall embody a mechanism of novel construction and arrangement by which music sheets may be readily turned to expose one or the other of their sides, and by which the music sheets may be furthermore turned simultaneously in one direction when it is desired to repeat the score.

The invention further proposes a music leaf turner which shall comprise a frame readily applicable to a music rack or stand of ordinary construction, and which shall further include a plurality of leaf turning elements operatively connected with a turning mechanism of novel construction, arrangement and operation.

With the above and other objects of similar nature in view the invention consists in the combination, construction and arrangement of parts, set forth and falling within the scope of the appended claims.

Referring now more particularly to the Speccation of Letters Patent.

K backing strip Patented Aug. '7, 1917.

Serial No. 102,243.

accompanying drawings, the invention is shown generally at 10 and comprises two skeleton frame sections 11 and 12 respectively, which sections are hingedly connected together as at 13 whereby they may be readily folded to dispose the device in relatively compact form when not in use.

Stretched across each of the sections 11 and l2 at spaced intervals are wires 141 against which the sheets of a music score are adapted to rest, while said sections are furthermore provided with spring clips 15 arranged to clamp the back sheets of the score against displacement from the sections. The Section 11 is further provided adjacent one end with a relatively wide backing strip 16 arranged transversely thereof and suitably secured in any desired manner. For holding the sections in set-up position there is pivoted to the rear face of the backing strip a latch element 17, a pin 18 being carried by the adjacent side of the section 12 for detachable engagement by said element.

For turning the several loose sheets of the music score, there is provided a plurality of similarly constructed turning elements 19, each consisting preferably of a single length of wire bent to coincide with the top, bottom and outer side portions of the sections. These elements are hingedly carried by the section 11, an end portion of each being directed inwardly of said section as indicated at 20 and journally engaged in suitable bearings 21 carried by the section and by the 16. The other end portions of the turning elements terminate in eyes 22 pivotally engaged about the inwardly directed ends of the other element outwardly of the section.

F iXed to the terminals of the inwardly directed portions 2O of the turning elements are pinions 23.

For actuating the turning element the following mechanism is employed. Secured to the front face of the backing strip are spaced plates indicated respectively at 24 and 25. These plates are each provided with a pair of outwardly directed ears 2G, having formed therein a pair of openings 27, said openings alining with respective openings in the corresponding ears of the other plate.

Slidably engaged through alining openings in corresponding pairs of ears 26 are relatively movable rods 28 and 29, the former being provided at one end with a rack 30 meshing with the pinion 23 on the related turning element whereby when said rod is moved in one or the other direction, said turning element will also be moved in a corresponding direction. Encircling the rods 2S are spaced pairs of coil springs 31 Xedly connected at their outer ends to the rods while their inner ends are free to move therein. Carried by each of the rods 29 intermediate its ends is a yoke member 32 the legs of which embrace the rod 28 between the springs 31. Said yoke is movable with the rod 29 in a manner to be described whereby to compress one or the other of the springs 31 and consequently force the rod 28 in a corresponding direction to actuate its turning element.

For operating the rods 29 there are pivoted as at 33 to the plate 24, bell crank levers 34, the arms of which are respectively connected with the rods 29 and, through the Ymedium of links 35, with the actuating elements 36 and 37. For mounting the elements 36 and 37 on the backing strip 16, there is secured to the outer face of the latter'a plate 38 provided at its ends with laterally turned ears 39 having alined bearing openings 40 formed therein.V rlhe element 36 comprises a sleeve 41 journaled in said bearing openings 40 while the element 37 consists of'a Vrod'42 rotatably engaged through said sleeve,'the inner ends of the elements being connected as at 43 to the respective links 35 While carried at their outer ends are finger pieces 44 each consisting of oppositely directed arms 45V terminating in push buttons 46. Y

Thus by pressing the top button of the elements 37 and 36 in order, the loose'sheets of music are turned in one direction, while by pressing upon the lowerbuttons in order thesheets may be returned to their initial position. Should it be desired to repeat the entire music score theloose sheets'may be simultaneously turned to their initial position by pressing upon the lower button of Athe element 37, there being carried by the arm of said button a lateral extension 47 overlying the lower arm of the element 36 so that when said element 37 is actuated the element 36 will likewise be moved.

Y For securing the loose sheets of the music score t-o the turning elements there are fixed to ythe sides thereof spaced fingers 48 while coperating with said fingers are spring pressed clamping members 49 each consisting preferably of a single length of wire bent into substantial U-shape with their legs looped to pivotally receive the elements and "terminating in lateral extensions 50, yieldably held in clamping relation with the fingers. The turning elements further carry at their upper sides spaced arms 52 between It will beunderstood, when moving the 55 adapted to receive one or the other end of the spring whereby it will "beheld at its limit of movement in either direction.

For releasing the rod 29 after the turning element has been carried beyond its Vcenter of movement, there is provided on the oppo- Vsite'end of the rod 28 from the rack 30 a U-shaped clip 56 straddling the rod 29 Ybetween the ends of the spring 55. Y

Thus as the rod 28 is moved under the influence of the compressed spring 31, to actuate the turningfelement, the clipv 56 moves also with the rod to carryone'of its legs 'between the rod 29'and one or thev other end `of the spring 31, said end being in 'this manner disengaged from the notch sothat the rod 29 will be'free to move in the opposite direction'to compress the'other of the springs.

What is claimed 1. A music leaf 'turner comprising a frame, a leaf carrying element hinged to the frame, relatively movable rods carried by the frame, means resiliently connecting said rods, operative connections between one of the rods and said carrying element, means for actuating the other of said rods, and
